ll'his invention relates toan improved teeth cleaning unit and moreparticularly to a teeth cleaning assembly wherein the toothbrush and allaccessories necessary for'the proper care of teeth are assembledtogether in a compact and attractive unit which may be convenientlycarried in the pocket or purse.

Proper care of the teethrequires daily brushing and cleaning of theteeth which should be done after each meal. Such preferential carecannot be given to the teeth by most individuals since the necessaryimplements, such as the toothbrush and accessories used by suchindividual, are not ordinarily carried by the individual or otherwiseare not conveniently available or accessible throughout the del It isthe purpose of this invention to provide a teeth cleaning assembly whichpresents in one compact, convenient and attractive unit, a toothbrushwith the necessary complement of toothpaste or powder contained in acartridge sanitarily housed within a'sealed and dustproof compartment inthe handle section of the unit, and which handle section additionallycontains a sanitary compartment for housing and containing the brushbristles. and a compartment wherein moisture absorbent and disinfectantmaterial may be contained which serves to extract. the moisture carriedon the used brush and maintain the bristles at all times in thoroughlydisinfectant condition. The unit, including the toothbrush and teethcleaning accessories, is assembled in a compact and sturdy manner and isof such size and form that it may conveniently be carried in the pocketor purse at all times. The unit can be moided'into various attractiveforms from available plastic materials, and is so constructed that thebristles may be fully protected from dirt, contamination and damage, andmaintained at all times in thoroughly sanitary and disinfectedcondition. The teeth cleaning unit assembled in accordance with thisinvention encourages and makes convenient the proper cleaning and careof the teeth.

In order that a clearer understanding of this invention may be had,reference is made to the accompanying drawings in which:

- section 4. The handle section is provided with a compartment a adaptedto receive and contain the toothbrush bristles, a compartment 6 adaptedto contain a drying and disinfectant agent in communication with thebrush receiving compartment a, and a dentifrice compartment 0 which iscompletely sealed oil. from the brush compartment :1 and in whichadentifrice cartridge 0 may be contained and fully protected fromcontamination and moisture. The open end of the dentifrice compartment 0is closed by a closure cap which may have associated therewith a dentalfloss dispenser d from which dental floss 1 may be readily withdrawn.

Referring more particularly to the teeth clean- N ing unit asillustrated in Figs. 1 to 8 inclusivj of the drawings, the brush sectionI comprises a member or stem 2 formed from a suitable plastic to whichtwo or more rows of brush bristles 3 are flrmly secured. The stem 2 ishinged at one end thereof to one end of the handle section 4; the stem 2being of sumcient length to permit easy cleaning of the teeth withoutrequiring insertion into the mouth of any substantial part of the handlesection 4.

The handle section l may be attractively shaped and formed from suitableplastic resins, such as phenolic or urea resins or styrene plastics wellknown in the plastics art. The handle section 4 is provided with arounded back wall 5 and parallel extending rounded side walls 8 unitedto the back wall 5, thereby presenting a member of generally roundedU-shaped cross-section. The drying and disinfectant compartment b ispositioned at the upper end of the handle section and is provided with afront wall I set between and joined to the side walls 6 so that thecompartment b has an enclosed cross-section formed by the joined frontwall 1, side walls 6, and back wall 5. The upper end of the compartmentb is closed by an end wall 8 which seals oil the upper end of the dryingand disinfectant compartment 2). The upper end 9 of the back wallsection 5 may. be given an attractively curved contour, as shown moreparticularly in Figs. 1, 2 and 4 of the drawings, so that the upper endof the handle section has a smooth merging transition toward theextended stem 2 of the brush section.

The lower end of the brush stem may be provided with two or more spacedand generally cylindrical bosses III, which seat between the rounded endextensions l l of the side walls 6. An intermediate extension II, whichmay be integrally formed with the end wall 8 of the handle section,projects from the end wall 8 between the spaced bosses iii. A hinge pin12, extending through the cylindrical bosses l and the intermediateextension ii', is secured to the rounded extensions l I of the sidewalls 6 so that the stem 2 may pivot or hinge on the pin l2. The endwall 8 of the handle section may be given a rounded or curvilinearcontour which closely conforms to the cylindrical surface of the bossesl0, thus permittingunobstructed swinging movement of the stem 2. Thestem 2 is provided with a pair of spaced shoulders i3 at the end thereofadapted to seat against the shoulders I! at the upper end of the handlesection, thereby to limit rearward swinging movement of the'brush stem 2beyond the point where the longitudinal axis of the fully extended brushstem is in alignment with or generally parallel to the longitudinal axisof the handle section. The hinged pin I2 is provided with headed ends lwhich press the rounded extensions ll of the side walls 6 and theintermediate extension li' into frictional engagement with the ends ofthe cylindrical bosses in of the stem, thereby providing for frictionalresistance front wall 20 which is joined to the side walls 8.

. These walls may be rounded in contour so as to give the dentifricecompartment a tubular form.

It will be appreciated that the enclosing walls which define the brushcompartment a may also, if desired, be rounded in form so that theentire handle section is substantially cylindrical. An

air-tight wall 2| is Joined to the upper end of the front wall 20 and t0the adjacent back wall 5 and side walls 8 to seal 011 the dentifricecompartment c from the brush compartment a. Thus no moisture from thebrush compartment a can enter the dentifrice compartment 0.

As shown more particularly in Figs. 1, 5v and 8d, the dentifricecartridge may be of the ejector type, adapted to contain the dentifricein the form of a solid stick 22. The lower end of the dentifrice stick22 seats in a cup shaped receiver 23. A pin 24 projects from the sidewall of the.

cup receiver 23 and through a slit 25 extending longitudinally along theside wall of an enclosing tubular protective member 26. A frictioncoilar 21 is fixed to the lower end of the tubular member 28, so formedthat the collar 21 will frictionally grip the enclosing walls of thedentifrice, chamber 0 when the tubular member is telescoped therein, asshown more particularly in Figs. 1 and 5.

It will be appreciated that when the dentifrice cartridge p is withdrawnfrom the chamber c, the pin 24 may be readily manipulated by the fingerto extend the end of the dentifrice stick 22 so as to project from theupper end of the tubular member 26, and thus made readily acccessible tothe user. The proper quantity of dentifrice may be readily deposited onthe brush bristles 3, by first moistening the bristles and stroking thebristles over the projecting end of the dentifrice stick. The tubularmember 21 may also be provided with a knurled rim 21', providing afinger grip which facilitates insertion and withdrawal of the dentifricestick containing section of the tubular member 24 into and from thechamber 0.

It will be appreciated that dentifrice stick con- Dental floss may beconventiently supplied by the provision of a dental floss dispenser dwhich may take the form of a cup 28 fixed or formed on the end of thetubular member 24. Thebottom of the floss cup 28 may be provided with apin hole 29, from which the string of floss contained in the cup 28 maybe withdrawn. Sections of the floss string ,f may then be broken off inthe lengths desired.

When the brush section I is folded into closed position as shown inFigs. 3, 4 and 5, it will be noted that the brush bristles 3, which maytoe inwardly, are neatly housed within the brush compartment a,protected by the back wall 5 and side walls 6 of the handle section. Asshown more particularly in Figs. 5 and 8, the side walls 6 are formed toslightly overlap the adjacent sides of the brush stem 2 so that when thebrush stem has been folded to house the bristles within the compartmenta, the open front wall of the compartment a is fully sealed oif by thestem 2, thereby preventing the entry bf any dirt or contaminant intothis compartment, and further preventing the escape of moisture from thecompartment a which might otherwise wet or dampen side walls 36, andcompartment wall disinfectant compartment 1), thereby limiting anddefining the housed position of the brush bristles 3 in the brushcompartment a. The stem 2, when in closed position, is partiallytelescoped between the edge portions 6' of the sidewalls 8, which edgeportions are made to frictionally grip the side faces of the stem 2 tofurther retain the 7 brush section in folded closed position.

The compartment b is designed to contain a assailed drying agent of highmoisture absorption qualities designed to absorb moisture vapors fromthe "brush bristles which pass through the apertures it in thecompartment wall l8, which vapors are absorbed by the drying agent. Thusthe brush section may be folded into closed position immediately afteruse, with the assurance that the brush bristles will be dried whilecontained in the brush compartment (1 by the high moisture'absorptivecharacteristics of the drying agent in compartment b. The drying agentcontained in the bristles are kept in a thoroughly disinfectantcondition. 7 Due to the novel construction and arrangement of the handlesection, dirt and foreign matter are also prevented from entering thecompartment a.

It will be further noted that no moisture carried by the brush bristleshoused within compartment .0 can reach or enter the fully sealeddentifrice compartment c. The dentifrice compartment c can be made ingenerous proportions so that the dentifrice cartridge P can be made in asize to contain several days supply of dentifrice.

-There is shown in- Figs. 9, wand 11- a teeth handle section has asmooth merging transition to the extended stem I of the brush section.

The upper ends of the side walls It may be provided with roundedextensions ll through which the-hinge pin l2 extends. The spacedcylindrical bosses Ill at the lower end of the brush stem 2, seatbetween the rounded extensions ll of the handle side walls 38. Theintermediate extension ll projecting from the end wall 8 of the handlesection, extends between the spaced bosses Id. The hinge pin I 2 havingheaded 'ends Id, extends through the spaced bosses it, and theintermediate-extension H, and the side wall extensions i i. so as tohingedm secure the brush section i to the handle section in a manner toprovide frictional resistance to the hinging movement of thebrush-section. As heretofore described, the stem? is provided withshoulders I: at the end thereof adapted to seat against the shoulders llat the upper end of the handle section to limit the rearward swingingmovement of.

the brush stem.

The open brush compartment (1 is defined by the side walls 36 and thecompartment wall 5|, providing a brush receiving cavity of generallyU-shaped cross-section. The lower end of the compartment .a is closed byan end wall 52 joined to the adjacent side walls '36 and thelongitudinal compartment wall ii. The upper end of the brush compartmenth is defined by a closure wall 40 which may have flanges l1 shaped tofrictionally engage the surrounding and enclosing walls 38, 31 and II ofcompartment b. The closure member 48 is provided with holes orperforations ll which communicate with the brush compertinent a. Theclosure member 46 may be made removable so that the drying anddisinfectant agent contained in compartment b may be replaced andreplenished. I It will be noted that when .the brush section is inclosed position as shown in Fig. 11, that-the brush bristles 3 areneatly contained and housed in the bristle compartment 11.

' anc\that a portion of the brush stem will rest .upon

cleaning unit in which the handle section 4 has a somewhat modifiedcompartmental arrangement which permits the handle section to be made;somewhat shorter in length but larger in crosssection than the handlesection 4 previously 'de-' scribed. The construction as shown in Figs.9, 10 and 11 also permits use of a brush section I having a somewhatlonger stem 2. The handle sec- 'tion 4 here shown may also beattractively shaped and formed from moldable plastics.

The handle section is defined by a back wall 35 and parallel extendingside walls 36 united to the back wall 36. A longitudinal compartmentwall II is joined to the side walls 36 midway of their width so as todefine a rear dentifrice compartment 0 adapted to contain the dentifricecartridge p. The drying and disinfectant compartment b is positioned atthe upper end of the.

handle section and is provided with a front wall 31 set between andjoined to the side walls 36, so

that the compartment b presents an enclosed cross-section formed by thejoined front wall 31,

The upper end of the compartment b is closed by an end wall II which isjoined to the front wall 31,

the front wall 31 of the drying and disinfectant compartment 17, therebylimiting and defining the housed position of the brush bristles 3 in thebrush 2 is also partially telescoped between the side walls 9 "so thatportions 36 of the side walls will frictionally grip the side faces ofthe stem 2 to retain the brush section in foldedlclosed position andprevent the entry of foreign matter into the brush compartment a.

When the brush section has been folded after use into closed foldedposition, the drying agent contained in compartment b draws of! andabsorbs the moisture vapors from the brush bristles which pass throughthe holes 48 in the closure 48 and are absorbed by the drying agent incompartment b. The disinfectant material contained in compartment 12gives off disinfectant vapors which percolate through the apertures 48in the closure wall 38- to disinfect the used brush bristles housed incompartment 41.

The dentifrice compartment 0 may be closed at the open end thereof by asuitable closure cap 53 provided with a threaded collar 54 which screwsinto the threaded end of the compartment 0. The closure cap 53 may alsobe provided with a dental fioss dispenser d in the form of a cuptelescoped into the surrounding knurle collar portion. of the capclosurei L A modified form of dentifrice containing cartridge p is illustratedin Figs. 10 and 11 of the drawings which may be either formed separatelyfrom, or as a part of, the closure cap 53. The dentifrice cartridge maycontain dentifrice in paste or. powder "form, which can be withdrawnfrom the cartridge or tube upon opening one end thereof. It will beappreciated that numerous diil'erent types of dentifrice containingcartridges, containers or receptacles may be used as desired inconnection with-my improved teeth cleaning unit. The ejector typecartridge adapted to contain a solid dentifrice stick as previouslydescribed is, however, my preferred form.

It is now seen that an improved teeth cleaning unit has been providedwhich can be economically formed and shaped from a variety of moldableplastics to provide a neat, compact, and attractive unit adapted to becarried in the pocket or purse. Moisture vapors resulting from moistureor water deposited upon the bristles during use is drawn off andabsorbed by the drying agent in compartment b. Thus, the brush bristlesmay be automatically dried when not in use. The compartment b may alsocontain a vapor producing disinfectant which vapors may flow from thecompartment b into brush compartment through the perforated dividingwall therebetween, thereby effecting a thorough sterilization of thebrush bristles. The brush compartment is fully closed when carried inthe-pocket or purse by a, portion of the stem of the brush section, thuspreventing the entry of foreign matter or contaminants into the brushcompartment a or the escape of moisture from the compartment a, whichmight otherwise soil the pocket or purse in which the unit is carried.

It will be further noted that the dentifrice compartment c is completelyenclosed and sealed oil? from the brush compartment 11 and the dryingand disinfectant compartment b, thus assuring a clean and drycompartment or cavity in which the dentifrice cartridge may becontained. The dentifrice compartment c is of generous size and isadapted to contain a selected dentifrice cartridge of a size which willcontain a generous supply of dentifrice. The dentifrice cartridge p ispreferably designed to contain the dentifrice in stick form. However,the unit may be designed to carry a dentifrice cartridge in the form ofa tube or container for powder or paste dentifrice.

The dentifrice sticks or tubes or containers of powdered or pastedentifrice, may be supplied and sold in dozen lots, packed in aconvenient carton, and from which supply the user may periodicallyreplenish the dentifrice cartridge in compartment b. A dental flossreceiver or cup d may be associated with the unit from which a sectionof dental floss may be conveniently withdrawn. The teeth cleaningassembly as thus provided is a highly convenient and attractive unit,constantly ready for use wherever the user may be, and which presents inthis compact unit all implements necessary for the proper cleaning andcare of the teeth.
